Active clinical trials for "Infections"

Cytomegalovirus (CMV) is a common virus that usually presents with few if any side effects. When first infected, some people may have symptoms similar to mononucleosis (i.e., fatigue, weakness, fever, swollen glands). Most people in the United States are infected during childhood or as adults if they work around children. Pregnant women, who have not been infected with CMV in the past and become infected during pregnancy (i.e. a primary infection), may cause their babies to get infected with CMV. Babies that are infected may develop permanent disabilities including hearing loss and a small portion will die from the infection. Currently it is not routine practice to screen pregnant women for CMV infection. Additionally, there is no agreement about how to evaluate and manage pregnant women infected with CMV for the first time. There is also no evidence that treatment is beneficial for the baby. The purpose of this research study is to determine whether treating pregnant women who have a primary CMV infection with CMV antibodies will reduce the number of babies infected with CMV.

Many solutions are used for cleaning the skin of a patient previous to a surgery. Although the efficacy of clorhexidine has been proved in other surgical procedures, there is only a retrospective study in cesarean section (they report no benefit of one solution over the other). The investigators would like to evaluate the difference in surgical site infection in patients after cesarean section comparing preparation of the skin with clorhexidine versus povidone.

To evaluate the efficacy and safety of fixed combination of azithromycin 1.5% + 0.5% Loteprednol eye drops for the treatment of ocular inflammation and infection associated bacterial blepharitis and / or keratitis and / or conjunctivitis compared with the individual administration of azithromycin 1.5% and 0.5% Loteprednol (separately).

To explore the antiviral effect of nucleoside analogue in late pregnancy and the safety of the antiviral drug to fetus.To establish the best therapy strategy to pregnant women with high level of HBV DNA.

PROBIC Rationale: Procalcitonin measurements can reduce the number of blood cultures in the ICU. Objective: The investigators suggest that PCT is a marker for blood stream infection in all patients in the ICU in whom attending physicians/ intensivists order blood culturing in the suspicion of microbial infection. The investigators want to demonstrate that its use for guiding blood culturing is cost-effective and safe compared with blood cultures alone. Study design: Prospective, non- inferiority, multicenter, single-blinded, cluster- randomised cross-over clinical trial. Intervention (if applicable): The intensive care units will be allocated into two groups: a control group (blood culture) and the intervention group (procalcitonin). Main study parameters/endpoints: Safety, expressed as mortality at day 28 and 90, with a mortality difference not exceeding a between groups difference of 10% by non-inferiority analysis. Cost-effectiveness, expressed in euro, calculated by deducting costs of procalcitonin testing from saved blood cultures compared with standard treatment spending on blood cultures in the control group. ICIS Rationale: The aim was to evaluate the Intensive Care Infection Score (ICIS) in predicting microbial infection and its sequelae in critically ill patients in whom attending physicians/ intensivists order blood culturing in the suspicion of microbial infection. Objective: Because of the complexity of the pathophysiology of systemic inflammation it is unlikely that a single parameter will have sufficient diagnostic accuracy for infection. Therefore we will study combining parameters producing a diagnostic score. Study design: Prospective, multicenter, cohort trial. Supplement for the control arm of the ProBIC study. Intervention (if applicable): Blood is drawn for daily routine laboratory measurements and collected in K3EDTA aliqnots. The ICIS score is composed of five blood-cell derived parameters which can be extracted using the same aliqnots. Main study parameters/endpoints: To develop and evaluate a blood- cell derived score to enable the diagnosis of microbial infection, its likelihood, its invasiveness and severity.

This cluster-randomized prospective study will evaluate the effect of hygiene-based intervention strategies on the incidence of overall SSTI and MRSA-associated SSTI among military trainees. The proposed interventions used singly or in combination include standardized training and education, and weekly chlorhexidine showers.

The goals of our study are to critically evaluate if a healthy population supplemented with Transfer factor experiences fewer incidences of colds and flu, or experience shorter duration of illness compared to an identical population taking placebo. In this study we will give either Transfer factor or a placebo to two groups of healthy adult men and women for a period of 7 weeks in a double-blind experimental design. The frequency and duration of colds and flu-like symptoms will be recorded during the course of the study. Saliva samples will be collected weekly and assessed for salivary IgA secretion rate. Data from this study will establish the efficacy of Transfer Factor to support a healthy immune system.

The purpose of this study is to examine the efficacy of a dilute betadine solution in reducing infectious complications in revision total knee arthroplasty. The investigators will enroll patients who are scheduled to undergo a revision total knee arthroplasty. Patients will be randomized into two groups. The treatment group will receive a dilute betadine lavage prior to surgical closure for 3 minutes followed by 2000ml of sterile saline irrigation and the control group will receive the 2000ml sterile saline lavage alone.

The purpose of this study is to determine whether repeated courses of sulphadoxine-pyrimethamine (SP) in combination with azithromycin given at Antenatal Clinic, leads to lower rates of low birth weight deliveries (<2.5 kg) among Papua New Guinean women, than the current standard treatment of SP and chloroquine.

The specific objectives of this investigation are to assess the effectiveness of daily gargling and vitamin D supplementation as preventative measures against incident upper respiratory tract infection (URTI) in students attending McMaster University. Investigators hypothesize that Vitamin D3 supplementation will decrease the incidence of symptomatic upper respiratory tract infections in university students Gargling will decrease the incidence of symptomatic upper respiratory tract infections in university students.
